HENRY C. WORK, OF PHILADELPHIA, PENNSYLVANIA.

Letters Patent No. 96,531, dated November 2, 1869.

IMPROVEMENT IN KNITTING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

will enable others skilled in the art to make and use the same, reference being had to thepaccompanying drawings, forming part of this specification.

The obj ect of this invention is to provide certain iinprovements inknitting-machines, calculated to simpliy and cheapen the cost of the same.

rlhe invention comprises a means of operating both the hooks' and sliding-pins by one cam on the cylinder; and v It also consists of a v'uzuproved arrangement of yarnguide, in lconnection with the handle for turning the cam.

Figure 1 represents a sectional elevation of my improved knitting-machine;

Figure 2 represents a plan view of the same;

Figure 3 represents a horizontal section, taken on the line x x; and

Figure 4 is a cross-section of the pin and hook, taken through the line y y of fig. 1, said part-s being shown enlarged.

Similar letters of reference indicate corresponding parts. i

A represents a vertical-revolving cam-cylinder, and

B, a central tube, through which the fabric passes.

a representsvthe hooks, which rise to receive the yarn and form'the loops, by drawing the yarn down over the top, c, of the central tube, in the usual way.

b represents the sliding pins, working on the needles 0r -in grooves in the fronts of' the needles, 01 the heads of these pins may be grooved, to fit partly around the hooks. p

. These pins are arranged to rise above the to'p' of the cylinder just previous to the going down of the hooks, so as to take under the loops d, already on the hooks, andhold them away, to allow the hooks to pass down with the yarn to form the new loops. After the hooks have passed below, the pins recede and cast oli' the loo s.

'Ilhese pins take the place of the latches and springhooks commonly employed, and are much more reliable in action, and less liable to get out of repair.

The shanks ofthe hooks, below the top of the cyl me, this inder, are bent, as represented at e, in the direction opposite to that in which Athe cam-cylinder moves, and

they are connected with the cam D below the bends. Betweeuthe two vertical parts of the hooks, the pins b are connected to them, as shown at j, so that they 'are moved by the said hooks, and consequently by the same cam. But they are so arranged that Athe pin connected to one hook rises at the top of the cylinder in the position to act in conjunction with theA succeedingli'ook, whereby the hooks always rise and are drawn down in advance ofthe pins. l

. The distance travelled vertically by the pins and the hooks is equal, but the pins are not required to rise as high above the cylinder as the hooks, and they are therefore made4 shorter.

My improvement in the yarn-carrier.consists in ina ing use ofthe handle E, by which the cam-cylinder is turned, for the said carrier, by providing a guide-pas v sage through the same'for the yarn, and conducting the yarn from the bobbin through it, and a guide-eye, F,

attached to the crank nearer the point of delivery t l the hooks.

This machine is intended more es ieeiall f for a small cord-knitting machine, for the amusement of children, but it is applicable for work of any size. In larger machines, however, where the hooks would require to be closer together, the bent part of the shanks of the hooks may require to be extended further back, and instead of carryingthe pins for the rst succeeding hooks, the said pins may be arranged to act with the second or third succeeding hook.

Having thus described my invention,

I 'claim as new, and desire to secure by Letters Patent- 1. 'Ihe combination ofthe hooks c and pins b, when connected as described, so that both are operated by the same cam, and so that each pin operates upon the loop of yarn on the hook next to that one to which'the said pin is connected, substantially as specified.

42. The arrangement, in the crank-handle, of a yarnguide, substantially as specified.

The above specitication of my invention signed by day of 1869.
